STORE-FRONT CONSTRUCTION.

Applicationfiletl May 15, 1925. Serial No. 30,471.

This invention relates to a store front construcution. particularly to aconstruction for n'iounting the plate in these construe tions. It hasfor an object to provide a constructirm oi this character which willyield to relieve the strains on the glass without breakage, and in whichthere are no screws under the edge of the glass, so that should thesupporting blocks fail the glass cannot rest on the screws and becomebroken;

it is alsoan object of the invention to simplify the construction sothat it may be much more easily installed, doing away with a number ofthe operations required in the old constructions, and thus will be muchcheaper to install.

It is a further object ot the invention to provide a construction ofthis type in which there is a definite stop or locating element whichmay be accurately located for the purpose of aligning the supportingstructure, and thus prevent strains on the glass by tightening thesupporting members and preventing breakage. v

Nit-h the foregoing and other objects in View, I. have devised theconstruction illus trated in the accompanying drawing form ing a part ofthis specification, similar reference characters being employedthroughout the various figures to indicate corresponding elements. Inthis drawing,

Fig. 1 is a perspective view showing my improved construction installed,and with one end in section.

Fig. 2 is a transverse section through the construction.

Fig. 3 is a side elevation ot the outside molding looking from theinside thereof, and

Fig. 4t is a transverse section through the molding substantially 011line 4l-al of Fig. 3.

In the construction shown the member 10 is a wooden sill member providedin its top surface with a longitudinally and upwardly extending stop orlocating lip or rib 11. This sill is "formed accurately to size andshape and then a strip of sheet metal 12, preferably copper, is drawnonto this sill in a die so that it accurately fits the surface of thesill member. This covering of sheet metal extends over the lip or rib 11and out around the forward edge, and then around and under the rib 13 onthe under side of the sill at its forward edge, so that this metalcovering is firmly held in place on the sill. At the inner side of theglass plate 1 1i is a sheet metal bar 15 bent substantially to the shapeshown, the top wall being concave at 17 near the surface of the glass toform a gutter for drainage purposes, and then extends down 'ardly toform a wall 18 to engage the surface of the glass. It is then bentbackwardly over the top of the lip 11 and then downwardly as shown at 19to form a shoulder to engage the inner wall of thelip, and to give astronger and better ported on the outside by a molding bar or sash 22bent substantiallyas shown in Figl, and this with the inner bar 15 aremade or. sheet metal, preferablycopper. At suitable distances throughoutthe molding are angle members 23 forming. supports for the molding barto prevent its free edges yielda ing inwardly and to hold it rigid. Theywill also form in effect feet for this molding bar to prevent it fromturning, so that it will stand up square against the glass and will alsohave a good footing on the top of the sill. The ends of the anglemembers 23 are set back oi the free edges or flanges 241-. and 25 of themolding baras shown in Fig. l, and brazed orsoldered thereto.

Ininstalling, the sill is mounted in proper position, and as the lip orrib llis accurate ly positioned it will form a definite stop or locatingmeans for the remainder of the structure. The inner bar 15 may bequickly and accurately located by means of this rib and the shoulder 19,and may then be secured by merely inserting the screws 26. The glass l lmay then be placed in position against the outer yieldable wall 18 onthis inner bar, and resting on any desired number of blocks 27 of rubberoi any other suitable material under the edge thereof. The molding baror outer sash 1nember22 may then be placed snugly against the outer wallof the glass, as shown in Figs. 1 an d Q, and secured by the obliquelypositioned screws 28 passing through openings in the bar and into thesill. Tightening up on these screws will tightly press the glass againstthe outer yieldable wall 18 on the inner bar. The glass is thusyieldingly mounted and will any more under expansion and contraction andwind pressures to equalize the strains so that the liability of breakageis reduced to a minimum. lerause ol the angle members 23 the outer sashmay be placed snugly against; the glass and there will be no danger ofits turning out o! position, and it will stand up squarely against thesurface ot the glass. It will be noted from Fig. 2 that. the screws 28do not pass under the edge of the gl' as so that should the blocks Eli'break or move out ol position the edge of the glass cannot engage thesescrews and thus become broken. It is also to be noted that there nowooden block required in the inner bar 15. The molding may be n-ovidedwith suitable vmitilatiug openings 99.

It will be apparent that this conz-=trtu-tion is very simple and thatthe operations required in installing are reduced to a mini' mum, butthat the glass is so n'iounteil as to yield to equalize the strains andpressures.

in the old types oli construction it is dill'i cult to properly locatethe glass slu porting bars, and especially to get them in properalignnient throughout the 'ij'rame so that when the are tightened up onthe glass the glass is not placed under lateral strain or broken. Withthis construction, however, the bars are practically self aligningbecause the lip or rib 11 is accurately made when the sill member ismade. Thus when the sill is installed this rib is in the proper positionand alignn'ient, and the inner bar i5 is accuratel; located by merelymoving the shoulder 19 against the inner wall of this lip. It is also tobe noted that by inclining the portion of the wall 30 upwardly betweenthe glass engaging wall 18 and the shoulder 19 a trough is provided forcarry ing away moisture which may pass to the inside of the bar, thiswall being provided with openings 31. It is further to be noted thatthis wall with the shoulder 19 forms a double check to prevent to alarge extent the passage of dust but at the same time allowing forventilation. llurthorn'iore, the lip ll etl'eetively prevents moisturerunning in from the outside.

.l'laving, thus set liorth the uaturoot nl v invention what I claimis 1. In awindow coustriuztion, a sill memher having a longitudinal,upwardly extending lip on its top wall, a. hollow sheet metal bar havinga yieldable side wall to engage one side of the glass and said yieldablewall havinga longitudinal shoulder to engage one side of the lip toposition the bar, and

a molding engaging the other side of the glass.

In a window construction, a wooden sill member having a longitudinalupwardly extending lip a sheet metal covering drawn over and covering;-one side edge 01? said member and said lip, a sheet: metal bar having ayieldable side wall to one e the glass: and said yieldable wall beingprovided with a shoulder to engage the lip to position the bar, and amolding to engage the other side of the glass.

8. In a window construction. a still memher, an inner sheet metal barhaving a yieldable front wall to engage the glass, means on the sill tocooperate with said yieldable front wall to position the bar, a sheetmetal molding bar on the other side of the glass, and means to teeming;the latter bar to the sill and pressing f; against the plush.

l. In a window ctuistruction. a sill member, an inner sheet metal barhaving a yieldable :lront wall. to engage the glass, means for securingsaid bar to the sill a sheet metal molgling' bar having one edge toengage the outer surface of the glass and another edge to rest on thesill, angle members extending; between said edges and forming supportsto prevent the molding turning on the sill and to retain it in an un-ight position, and means tor securing the molding to the sill.

5. In a window rlronsliructirm, a still m mher having; a loiuritiulinalupwardly extending; lip on its top wall. a sheet metal bar sooured tothe sill and having a yieldahle side wall to engage one surtace ot theglass, said yieldahlo wall also extending lau-liwartll over the rib andthen dmvnwardly to the sill to form a shoulder to engage the lip andposition the bar, a molding bar to engage the other side of the glass.and means for securing, the latter bar to the sill.

6. In a. window construction, a sill. member, a sheet metal bar securedto said sill memlier, the top wall ol said bar being" worn caved:uljacent its 'l'ront edge to form a trough and having? drain openings:therein, the trout wall ol' said bar extending downwardly to form agltiss engaging surl'a ee, then lawlnvardlv and upwardly to term a drainand then downwardlv to the :-ill n|umher, and a molding bar secured tothe sill to engage the other side of the lass.

In testimony whereof I allix my signature.
